SHOE-BUCKLE.

Specification of Letters Patent. Patented July 22, 1919.

Application filed November 23, 1917. Serial No. 203,557.

To all whom it may concern: 7

Be it known that I, BERNIE T. GRINDE- LAND, a citizen of the United States', residing at Mabel, in the county of Fillmore and State of Minnesota, have invented certain new and useful Improvements in Shoe-Buckles; and 1 do hereby declare the following to be a full, clear, and exact description .of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 3

This invention relates to buckles, and more particularly to buckles especially adapted for shoes and the like, and the primary object of the invention is to provide a buckle for shoe closures which will be simple and easy to operate, so that the shoe can be readily removed from and placed on the foot.

A further object of the invention is to provide an improved means for attaching the buckle to one edge of the shoe closure, so that the buckle cannotbe torn from the shoe upper.

Another object of the invention is to provide an. improved shoe buckle including a base plate carrying a pivoted clamp member having formed thereon a plurality of teeth for biting into the connecting member, and a reinforcing plate adapted to engage'the under surface of the shoe upper and having a pair of spaced integrally formed rivets, which are adapted to be inserted through the shoe upper and engage thebase plate, sothat the shoe upper will be securely clamped between the reinforcing plate and the base plate.

A still further object of the invention is to provide an improved buckle of the above character, which is durable and eflicient in use, one that is simple and easy to 1nanufac ture, and one that can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claim d and illustrated in theaccompanying drawing forming a part thereof, in which:

Figure l is a fragmentary 'front elevation of a shoe upperprovided with the improved buckle,

Fig. 2 is a longitudinal sectional view through the improved buckle,

Fig. 3 is a perspective view of the buckle, and

Fig. 4 is a detail perspective view of the reinforcing plate, showing the rivets formed integrally therewith.

Referring to the drawing in detail, wherein similar reference numerals designate correspondlng parts throughout the several views, the numeral 1 generally indicates the improved buckle, which is adapted .to be connected to a shoe or o-vershoe closure or upper 2. Each shoe closure is preferably provided with three or more of the improved buckles, so that the upper will be held tightly around thefoot of the user at all points. The buckles 1 are adapted to be secured adjacent one edge ofthe meeting edges of the shoe closure 2, while the flexible straps 3 are adapted to be secured to the adj acent'edge, and these flexible straps form means for engaging the buckles. Suitable fastening elements 4: are provided for holding the flexible straps 3 in position The improved buckle 1 includes a substantially fiat base plate 5, having its side edges bent upwardly, as at 6, to provide ears 7, which are provided with registering apertures 8, which rotatably receive trunnions 9 formed on the opposite side edges of the plate 10. The cars 7 are beveled rearwardly, as at 11, so that the plate 10 can be readily ri ed. The trunnions 9 are formed inte- Z5 grally with the plate 10, and are formed by cutting the side edges ofthe plate trans.-

versely and then rolling the cut portions toward the front edge of the plate, where the metal is'uncut. The forwardedge of the plate 10 is bent downwardly at right angles and cut to provide a plurality of biting teeth 12, the purpose of which will hereinafter fully appear.

A fiat rectangular reinforcing plate 13 is provided for attaching the buckle to the shoe upper, and this plate is positioned on the inner surface of the shoe closure directly beneath the base plate 5. The reinforcing plate 13 is provided with integral rivets i l on its side edges, and these rivets are formed by cutting the side edges of the plate inwardly toward the central portion of the plate,"and then bending the cut portion upwardly, as at 15, and rolling the ends of the cut portions toward each other until the rivets are formed. The base plate 5 is provided with a pair of spaced apertures 16, and the rivets are forced through the shoe upper and through said openings, and the same are then upset, as at 17 This formation firmly secures the buckle in position and clamps a relatively large portion of the shoe upper to the buckle, so that tearing of the buckle from the shoe upper is reduced to a mlnimum. I

In operation of the improved device the buckles are secured to the upper in the above-described manner, and the plate 10 is moved upwardly at right angles to the base plate, so as to position the tongues 12 par allel therewith, and the straps 3 are then inserted between the ears 7, and when the same are positioned at the desired point the plate 10 is thrown downwardly, which will forcibly bring the teeth 12 into engagement with the flexible strap, and thus prevent removal thereof. The rear end of the plates 10 engages the upper surface of the base plate 5 when the same is in its operative position, and a pull on the straps 3 will tend to throw the tongues 12 outwardly, and thus bring the rear edge of the plate 10 forcibly into engagement with the base plate, which will prevent any further movement of the tongues.

The base plate 5 is provided with a slot 18, which is positioned adjacent to and parallel with the front edge of the base plate, and this slot is adapted to receive a portion of the flexible strap 3, when the tongues 12 are forced into engagement with the same. The tongues depress the straps and force a slight portion of the same into the slot, which will efiectively hold the strap against movement. This slot 18 can also be utilized as a guide opening, when a relatively small strap is used, and in this instance the small strap is inserted through the slot 18 and thence brought over the top 17 of the base plate 5, and the plate 10 is then operated to forcibly bring the teeth 12 into engagement therewith.

In practice, I have found that the form of my invention, illustrated in the accompanying drawings and referred to in the above description, as the preferred embodiment, is the most eflicient and practical; yet realizing the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor clnnges in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention as set forth.

That I claim. as new is:

In a buckle of the class described, a flat base plate, upstanding ears carried by the base plate, a plate pivotally supported by said ears, a plurality of downturned teeth formed on the forward edge of said pivoted plate, said base plate adapted to be positioned on the outer surface of the article which is to be secured, rivets adapted to be forced through an article and secured to said base plate for securing said buckle thereto and forming a rest for a strap arranged to be engaged by the buckle to space the same from the base plate, thereby permitting the tongues to readily bite into the strap, and a flat reinforcing plate positioned on the inner surf-ace of the article directly below said base plate and connecting said rivets to prevent displacement thereof, as and for the purpose specified.

In testimony whereof I aflix my signature in presence of two witnesses.
